【摘要】 课题选用中远集团的三十万吨大型油船作为研究对象,以中国海事局最新颁布的STCW公约马尼拉修正案为标准,运用计算机仿真技术,建立软件与硬件相结合的锅炉混合仿真系统模拟器。根据机理建模的一般方法,首先详细分析了大型油船辅锅炉系统的结构组成和工作原理；然后以此为基础将整个辅锅炉系统进行必要的简化和子系统划分；根据不同子系统的特性,分别建立起相应的子系统仿真模型；最后再将各子模型按系统原理进行有机组合,构成锅炉系统的整体仿真模型。这样就运用集总参数分布式建模方法,建立起能够反映油船辅锅炉系统各种运行工况的动态数学模型。在已建立的锅炉系统动态数学模型基础上,运用C#编程工具在.NETFramework框架中进行模拟器软件设计。模拟器内部的全部控制逻辑皆来源于母型船上的辅锅炉系统,操作训练的内容与实船辅锅炉系统的操作完全拟合。模拟器实现的主要功能：主从锅炉的组合选择和并联运行、汽包水位控制调节、蒸汽压力控制调节、锅炉的手动/自动启动和停炉、参数高低限报警及系统自动保护。为了提高模拟效果,本课题设计出一套与软件相对应的模拟硬件系统。此硬件系统主要包括系统MIMIC流程控制屏和现场控制箱,涵盖油船辅锅炉系统的各主要子系统和相关设备,可以直观展示油船辅锅炉系统的工作原理和工况运行状态。将软件系统与模拟硬件系统进行组合控制,形成一个互联的锅炉系统模拟器。本模拟器具有功能完善、真实感强及操作便捷等特点,同时软硬件独立和联合运行均可实现整个油船锅炉系统的全工况演练和操作,满足中国海事局对于现行模拟器的要求。更多还原

【Abstract】 This paper selects300,000-ton-level VLCC of COSCO Group as the research target, uses computer simulating technology to establish a hybrid boiler simulating system with both software and hardware in accordance with the STCW78/10Manila amended Convention recently issued by Maritime Safety Administration P.R.C.According to the law of mechanism modeling, the thesis introduces the compositions and the basic working principle of the large tanker auxiliary boiler system firstly, and then takes this as the foundation to simplify the auxiliary boiler system and to divide subsystems. After this, establish the simulating model of each subsystem according to the different characteristics of their own. The divided sub-models are then put together organically to constitute the entire boiler simulating model. Thus the lumped parameter distributed modeling approach can be used to establish a dynamic mathematical model of the tanker auxiliary boiler system to reflect a variety of operating conditions.On the basis of the established dynamic mathematical model, using the C#programming tools of Microsoft.NET Framework to design simulator software. Internal control logic of the simulator is derived from the mother ship auxiliary boiler system, a high degree of fit is reached between the training content and the real ship. The main function to be achieved by the simulator includes the combination selection of master/slave boiler and parallel running, drum level control adjustment, steam pressure control adjustment, boiler manual/automatic start and shut down, high and low limit alarms and automatic protection of the system.In order to improve the simulating effect, a hardware system corresponding to the software system is designed. The hardware system mainly consists of the system MIMIC panel and control boxes, covering all major subsystems and related equipments of the auxiliary boiler system, which can directly show the principle of the tanker auxiliary boiler system and the working conditions.Software system and hardware system are combined to form an interconnected boiler system simulator in this paper. The simulator has a complete function, is more realistic and easy to operate. The system can run via the software and hardware separately or jointly. Drills and operations included in the full conditions of the boiler system can be achieved by either of the ways above, thus it can fully meet the standard of current simulator from the Maritime Safety Administration P.R.C.更多还原
